There is a wide range of definitions about anxiety currently, due to the amount of theoretical models and research from different points of view. Given this volumen of data, we consider very important to establish a thread that collects the most important considerations related to anxiety over time, since this review process will help us: (1) understand all variables that influence anxiety response; (2) to evaluate the proposed contributions from different approaches and the weight thereof; and (3) to try to unite them into an integrated insight. The gradual evolution of the concept of anxiey has managed to establish models in which it is posible to appreciate its interference in the attentional process. We will analyze, then, how paradigms related to anxiety address the problem of attention by creating new explanatory theories and measuring tools, and the results of its implementation. Finally, we will review all the proposed eplanations for the relationship between anxiety and attentional bias, from a critical standpoint, and trying again to build bridges with the aim of establishing an integrated view of all existing research.
